f-JPECIFZCATION forming part of Letters Patent No. 356.826, dared February 1. 1887- Applicaiion filed April 21, 1885. Renewed July 2.1, 1886. Serial No. 208,687. (No model.)

To aZZ whom ii; may concern.-

Be it known that 1, JOHN H. Fnnecson, of the city of Albion, county of Calhoun, and State of Michigan, have invented a new and useful Book-Leaf Holder, of which the following is a specification.

The object of the invention is to hold the leaves of a hook or sheet of music in place while on a piano, organ, or music-rack.

This invention relates to certain new and useful improvements in book-supports; and it consists in the peculiar combinations and the novel construction and arrangement of parts hereinafter more fully described and claimed.

Figure 1 represents a perspective view of my improved holder attached to the ledge of a musierack. Fig. 2 is a central vertical section of the holder detached.

Referring to said drawings, n represents a hook-clamp adapted to embrace a ledge of a music-rack or the like.

d d are set-screws passing through ears on opposite sides of the clamp, and by means of which it is detachably secured in position.

Between cars a c on the clamp works the lever b, fulcrumed in the pin 0. This lever is curved to correspond with the curvature of the clamp, and at its end opposite that which is fulcrumed it terminates in a cross-bar, 9, designed to rest against the book, (not shown.) near the margin thereof, as will be readily understood. The lever b is formed with a thumb-piece, I, extending from a point about midway of the cross-bar g, as shown, which thumb piece is designed for use in operating the lever.

e is a spring fastened to the clamp by means of the set-screw H. This spring bears against the lever, which is preferably flattened at the point of contact with said spring,- and the spring tends to keep cross-bar g in close contact or pressed firmly against the book.

What I claim as new isl. The combination, with the clamp a, of the lever b, pivoted thereto, and the spring e, pivoted to said clamp and bearing against said lever to press said lever in the direction of thearticle clamped thereby, substantially as and for the purpose specified.

2. The semicircular clamp A, provided with set-screws, the semicircular lover I), pivoted to said clamp and carrying the cross-bar g, and the spring 6, attached to said clamp and bearing against said lever to press said lever in the direction of the article clamped thereby, substantially as described.

3. The clamp a, set-screws (l d, passing through ears thereon, lever b, fulcrumed on the pin 0, journaled in ears formed on said clamp and having formed integral therewith the cross-bar g and thumb-piece I, and the spring a, secured to said clamp and bearing against the pivoted end of said lever to press said lever in the direction of the article clamped thereby, substantially as described.
